When Prince Ithaca of Cosmoralia and Princess Lilia of Ayodoya are married, it seems as though a great new age is about to dawn on the planet of Astria. Soon, however, the planet is invaded by a mysterious force of machines that seem to be determined to destroy humanity. Astria’s (and maybe humanity’s) only hope lies with the royal couple’s twin children, Jimsa and Affle, and with a number of individuals not native to Astria that they encounter after their respective escapes from the capital – a cyborg warrior named Il, a pair of robots named Arc and Beth and the enigmatic genius known as The Elder.
